Data corruption is the damage of information caused by various software or hardware failures. The moment a file gets damaged, it will no longer work accurately, so an app will not start or shall give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as fails are more likely to occur on larger in size hard disks where significant volumes of info are placed. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the bad file will be treated as a standard one and will be duplicated on all drives, making the damage permanent. A huge number of the file systems that operate on web servers nowadays often are unable to recognize corrupted files in real time or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the info uploaded in every single shared web hosting account that is created on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption thanks to a unique checksum for every single file. We'll store your info on a number of NVMe drives that function in a RAID, so exactly the same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file differs from what it should be, the file system swaps that file with a healthy copy from a different drive inside the RAID. There's no other file system that uses checksums, so it's easy for data to get silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you will not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption as all of our storage servers employ the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it'll be saved on a couple of redundant drives in a RAID i.e. the files will be the same across all drives. All copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, which would indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other disks. Even if there's an unexpected blackout, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, prolonging the time needed for the server to go back online. ZFS is the file system that can truly protect your content from silent data corruption.
